4140 / 4130 Seamless Mechanical Tubing are medium carbon alloy grades, which are widely used for many general purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum as alloying elements, combined with heat treatment, provides the combined advantage of hardness, ductility, and strength.4140 Meets ASTM A5194130 Meets ASTM A513 Type 5(DOM) A519 (CDS)Cut to Length available

Benefits of Round 4140/4130 Alloy Seamless Mechanical TubingSuperior tensile strength and toughnessHigh strength to weight ratioEasily heat treatable to a broad range of strength, machinability, and hardness.

Applications: aircraft components, hydraulic cylinders, rollers, structural apps, truck and automotive parts.
